I have done some research and have not been able to determine compatabality/performance for the following system. I have a Gateway FX510XT, Pentium 965 Extreme Ed.(3.73GHz,1066MHz FSB,2x2M cache,HT), on an Intel Motherboard w/975X 10/10/1000 LAN, with 4096MB PC5300 DDR2 667MHz SDRAM (4-1024MB modules, 1000GB (1TB) 7200RPM SATA II w/Raid 0 (2-500GB HDD) w/NCQ, 700-Watt Power Supply, running ATI Radeon X1900 CrossFire Ed. 512MB, Dual DVI, VGA Support with an ATI Radeon X1900 XT and an ATI Theater 550 Pro TV Tuner. My question is will an Ageia PhysX Card be compatable with this system and if so what would the performance expectations be? Does anyone know or can anyone refer me to a site that can answer this question? Thanks.
